Preparation and Characterization of Porous Electrochemical Senso...

A novel and sensitive electrochemical sensor based on porous pseudo-carbon paste electrode (PPCPE) for paracetamol detection is described. The physical and chemical properties of PPCPE are discussed in detail, the results show that the specific surface area of PPCPE with pores ranging from 2 to 5 Am in diameter is 59.26 m(2). g(-1). The obtained PPCPE possesses excellent hydrophilic. It was demonstrated that PPCPE exhibites a high selectivity and sensitivity toward paracetamol in comparison with
